vsPUT FOR BOILERS.

SPECIFICATION forming part of Letters Patent No. 351,660, dated October 26, 1886. Application filed November 19, 1835. Serial No. 183,305. (No model.)

.To aZZ whom t mayvconcerm Be it known that I, HENRY W. SHEPARD, a citizen of the United States, residing at Brooklyn, inthe county of Kings and State of New York, have invented certain new. and useful Improvements in Sputs for Boilers, of which the following is a full, clear, and exact description.

This invention relates to sputs for use more vided with a base-fiangc, which engages .one

side of the wall or heads of the boiler, and a lip projecting from said flange and adapted to be turned down over the other side of said wall or heads to firmly secure the sput in place, as I will now proceed to more particularly set forth and claim.

In the accompanying drawings, in the several figures of which like parts are designated by similar letters of reference, Figure l is a vertical section of a boiler provided with my improved sputs. Fig. 2 isa top plan View thereof. Fig. 3 is a sectional elevation of a die. and punch andsput arranged therein to illustrate one manner ot' applying my sput to a boiler. Fig. el is an enlarged sectional detail of my sputs applied to a dome-shapedhead of a boiler, the head being shown broken 'away at about the center.A Fig. 5 is a side elevation, and Fig. 6 a vertical cross-section, of mysput detached.

This sput consists, preferably, of a malleable casting having a base-flange, a, a central opening, b,which may be screw-threaded to receive a pipe-coupling, a wall, c, nnext adj acentto the threaded opening b, and next t'o the said wall and parallel with it a lip, d, projecting at about right angles from the base-flange, and sepa rated from thewall c by a-rectangular or sort of half-V space, e, so that the lip d is thickest next to the ange, and tapers thence to its up- 5o per edge.

My sput so constructed is applied to the boiler or other vessel as follows: An opening is -made in the boiler where it is desired to apply the sput, of a .diameter about equal to the diameter of the lip d on the plane of the ange, so that the sput may be applied by'inserting its lipped end through said hole until the ilange comes flush against the inside of the boiler. The sput is secured in place by a suitable punch and dic-for example, such as shown in Fig. 3, in which f is the die, shaped to receive the lower endof the sput, and g is a punch provided with a lip, h, shaped to enter the recess e and bear` against the inclined side of the lip d of the sput, and in the descent of the punch to turn over said lip d upon the boiler, and to spread or expand the metal of the sput and thereby effect a perfectly-tight union of the sput with the boiler.

Sputs designed for boilers having domeshaped heads will preferably have one half of the wall c higher than the other, in order that the sput may be put into the head with its opening b in a vertical line. (See more particularly Fig. 4.)

/Vhat I claim as my invention, and desire to. secure by Letters Patent, is-

l. A sput consisting of a malleable casting having a base-flange, a, a wall, c, a threaded opening, b, in said base and wall, and a lip, d, projecting from the base and standing ott' from the wall, substantially as described.

2. A sput having a base-flange, a central opening, and an adjacent lip, d, projecting from the ilange at about right angles thereto, and beveled or inclined on one side, substantially as described.

3. A sput consisting of a malleable casting having a baSeHange, a, a wall, c, a threaded opening, b, in said base and wall, and a lip, d, projecting from the base and standing off from the wall, combined with a boiler, substantially as described. I

In testimony whereof I have hereunto set my hand this 14th day of November, A. D. 1885.

HENRY W. SHEPARD.
